Answer:
1. X3, 15x - 10y = 80 15x - 7y = 51
-17y = 29
2. 8 = 1/60 + a. 8 - 1/60 = 7.98333333333
6 = 1/80 + b. 6 - 1/80 = 5.9875
13.9708333333

View graph
Step-by-step explanation:
The population refers to the whole set under study, while the sample is a representative part of that population.
You divide $4.55 by 7.
$0.65 times 9 = $5.85
<span>The graph of temperature versus pressure is a straigh line rising to the right. It Using the value above, the equation is P = 2.5522T + 699. The temperature is directly proportional to pressure. The pressure of the gas 0C using the equation,
</span>P = 2.5522T + 699
P = 2.5522(0) + 699
P = 699
Answer:
10.46
Step-by-step explanation:
Let the Number of additional pair = x
Ware house A :
855 + 92x - - - (1)
Warehouse B:
Initial cost per pair before 9
= 810 / 9 = $90
Additional 7% for pairs after 9
1.07 * 90 = 96.3
810 + 96.3x - - - (2)
810 + 96.3x = 855+ 92x
96.3x - 92x = 855 - 810
4.3x = 45
x = 45 / 4.3
x = 10.46
Additional pair be 10.46
